Product details

Why the 3.2A switch current matters for your boost rail

The TPS61087DSCR is a step-up (boost) converter with a 3.2A internal switch — that's the peak current the inductor sees, not the output current. For a 5V-to-12V conversion at 85% efficiency, that switch current supports roughly 800 mA output before hitting the limit. The 650 kHz and 1.2 MHz switching options let you choose: lower frequency for better efficiency (less switching loss), higher frequency for a smaller inductor (faster transient response).

Output voltage range and temperature grade

Output is adjustable from a 3V minimum to 18.5V maximum — that covers 3.3V, 5V, 9V, 12V, and 15V rails from a single Li-ion cell (2.5V to 6V input). No synchronous rectifier — the external Schottky diode carries the output current; pick one with a low Vf for the load current to keep efficiency up.

Package, footprint, and thermal path

Surface-mount only; no through-hole variant exists.

ROHS3 compliant.

Frequently asked questions

What is the difference between TPS61087DSCR and TPS61087DRCR?

The TPS61087DSCR and TPS61087DRCR share the same silicon and 10-WSON (3x3 mm) package. The suffix difference (DSCR vs DRCR) indicates reel tape-and-reel packaging variants — both are electrically identical. Confirm the reel quantity with your distributor for your production volume.

Is TPS61087DSCR compatible with the base TPS61087?

Yes — TPS61087DSCR is a specific packaging option of the TPS61087 base product number. The electrical ratings (3.2A switch, adjustable output to 18.5V, 650kHz/1.2MHz) are identical across all TPS61087 variants. The DSCR suffix denotes the 10-WSON package on a tape-and-reel carrier.
